New supernova: Hubble catches stellar explosions Posted: 09 Nov 2013 12:39 PM PST Supernovae are intensely bright objects. They are formed when a star reaches the end of its life with a dramatic explosion, expelling most of its material out into space. Another star has now exploded, forming supernova SN 2013ek.

Snap to attention: Polymers that react and move to light Posted: 09 Nov 2013 12:39 PM PST Researchers are investigating polymers that "snap" when triggered by light, converting light energy into mechanical work.

High-energy physicists predict new family of four-quark objects Posted: 08 Nov 2013 12:35 PM PST An international team of high-energy physicists says the discovery of an electrically charged subatomic particle called Zc(4020) is a sign that they have begun to unveil a whole new family of four-quark objects.

Key processes of photosynthesis simulated on quantum level Posted: 08 Nov 2013 09:47 AM PST Physicists have simulated key processes of photosynthesis on a quantum level with high spatial and temporal resolution. In their experiment with Rydberg atoms scientists discovered new properties of energy transport. This work is an important step towards answering the question of how quantum physics can contribute to the efficiency of energy conversion in synthetic systems, for example in photovoltaics.

Next-generation semiconductors synthesis Posted: 08 Nov 2013 09:46 AM PST Conventional processes for producing AIN layers run at temperatures as high as 1150 degrees Celsius, and offer limited control over the thickness of the layers. Now a new technique offers a way to produce high-quality AlN layers with atomic-scale thickness and at half the temperature of other methods.

A new scorpion species from ancient Lycia Posted: 08 Nov 2013 08:22 AM PST Scientists have discovered and described a new species of scorpion, Euscorpius lycius, coming from the area of ancient Lycia, nowadays the regions of the Mugla and Antalya Provinces in Southwestern Turkey. With the new discovery, the scorpions from this genus found in the country go up to a total of five known species.
